X platform problem

Hello,

I'm working with smart210 (linux qtopia system). I have an embedded video
application which use some X11 instructions. I found a lot of problems to
compile QT with X platform in my ubuntu PC. Also, I tried to use a basic
application which use the X11 library. I managed to cross compile the X
platform and to cross compile my basic application and after loading it
into my smart210, this application works but without any displayed result!!
But when I execute the same application in X86 Linux I see a window. How
could this happen? Is it possible to change the X11 instructions in
embedded application with a QT widget fonctions?

This may help. Qt normally uses it's own frame buffer.

Thank you for your reply. Well, I have to use the X plateform on my QT
video embedded Application. It seems that I can't make this with qtopia
root file system. So, I installed ubuntu in my smart210, it's easy to
install the x plateform on it but I have two problems with ubuntu, the
first problem is too heavy , the second one I can't use the capacitive
touch screen with it.

Also, I have another small question: Why when I download an ARM binary
(cross compiled by ubuntu desktop) on my ubuntu for smart210, it didn't
work? Is it a problem of compilers or what?

Hello,
 If you want to install Ubuntu in your 210 , you have to modify your Ubuntu
kernel .
